Iron and zinc exploitation during bacterial pathogenesis
TL;DR: This review describes the many elegant ways pathogenic bacteria mine, regulate, and craft the use of two key metals to build a virulence arsenal that challenges even the most sophisticated immune response.

Antiviral Resistance and Phage Counter Adaptation to Antibiotic-Resistant Extraintestinal Pathogenic Escherichia coli.
Keiko C. Salazar,Li Ma,Sabrina I. Green,Jacob Zulk,Barbara W. Trautner,Barbara W. Trautner,Robert F. Ramig,Justin R. Clark,Austen Terwilliger,Anthony W. Maresso +9 more
TL;DR: In this article, the authors demonstrate that E. coli sequence type 131, a circulating pandemic strain of Escherichia coli (ExPEC), rapidly develops resistance to a well-studied and therapeutically active phage (ϕHP3).

Murine Model of Chemotherapy-Induced Extraintestinal Pathogenic Escherichia coli Translocation
Sabrina I. Green,Nadim J. Ajami,Li Ma,Nina M. Poole,Roger E. Price,Joseph F. Petrosino,Anthony W. Maresso +6 more
TL;DR: This is the first report of a chemotherapy-based animal model of ExPEC translocation in cancerous mice, a system that can be readily used to identify important virulence factors for this process.

Escherichia coli Free Radical-Based Killing Mechanism Driven by a Unique Combination of Iron Restriction and Certain Antibiotics
TL;DR: It is demonstrated that combining subinhibitory levels of both iron chelators and certain antibiotics kills pathogenic Escherichia coli, and the mechanism of this effect is the production of supraphysiologic levels of reactive oxygen species, likely powered by the excessive import of iron.

Metals Enhance the Killing of Bacteria by Bacteriophage in Human Blood.
TL;DR: A role for circulating metals is defined as a major factor that is essential for the phage-based killing of bacteria in blood forMultidrug-resistant bacterial pathogens.
